Twenty-two Americans are said to have suffered mysterious injuries due to what U.S. officials believe were a series of sonic attacks. The Cuban government has denied having anything to do with the injuries.
The State Department has said it does not know who caused the attacks or why, but it ordered nonessential personnel and families out of Cuba late last month, leaving the embassy operating with a 60 percent reduction in its staff.
The agency also issued a travel warning to Americans not to visit the island, with which President Barack Obama restored diplomatic relations in early 2015 after five decades of isolation.
Last week, White House Chief of Staff John F. Kelly said the Cuban government “could stop the attacks on our diplomats,” but he declined to say whether Trump is considering fully shuttering the embassy.
